CROSS REFERENCE TO RELATED APPLICATIONS

This application is a continuation of U.S. patent application Ser. No. 16/549,850, filed on Aug. 23, 2019, which is a continuation of U.S. patent application Ser. No. 15/991,228, filed on May 29, 2018, the entire contents of which are incorporated by reference herein in their entirety.

BACKGROUND

The present disclosure relates to a hull and keel for a buoyant hunting decoy. More specifically, the hull and keel is shaped and weighted to provide improved and more lifelike characteristics of the buoyant hunting decoy.

Buoyant hunting decoys, such as duck, goose, and other waterfowl hunting decoys, are well-known hunting devices used by hunters to lure similar waterfowl to approach a water feature where the hunters may harvest them before landing. The hunter may use weighted lines to keep the decoys from floating away. In some configurations, hunters pull on an end of a jerk line to induce motion of the decoys to make the decoys appear to be more lifelike while floating in the water. However, many modern buoyant hunting decoys suffer from drawbacks that prevent or quickly dampen lifelike movements.

As shown in FIG. 1, a prior art buoyant hunting decoy 100 is depicted. The buoyant hunting decoy 100 comprises an upper portion 102 provided in the form of a duck. A generally flat bottom surface of the upper portion 102 forms a hull 104 of the buoyant hunting decoy 100. An elongate and continuous keel 106 extends downwardly from the hull 104 and includes a lower body 108. The lower body 108 extends laterally along a significant length of the buoyant hunting decoy 100 and is normally substantially hollow and commonly filled with sand to provide weight that keeps the buoyant hunting decoy 100 upright. The lower body 108 also commonly includes line retention slots 110 and/or holes 112 that may be used with weighted lines and/or jerk lines as described above. Due to the design specifications of the prior art buoyant hunting decoy 100, the behavior of the buoyant hunting decoy 100 is minimally lifelike and suffers from common drawbacks.

First, when floating in still water, the hunter is required to tug on the jerk line or the buoyant hunting decoy 100 will be unnaturally still. In many instances, the weight distribution is spread evenly along the length of the buoyant hunting decoy 100 and naturally dampens any bobbing type motion making the buoyant hunting decoy 100 unnaturally still. Second, even when there are small ripples in the water, the dampening behavior of the weight within the lower body 108 works against the motion of the buoyant hunting decoy 100 so that the motion is not lifelike bobbing of a duck in water. Third, when the buoyant hunting decoy 100 is placed in a stream with a moderate to strong current, the water passing between the lower body 108 and the flat hull 104 create hydrodynamic forces that cause the front of the buoyant hunting decoy 100 to dip deeper into the water, normally causing the head of buoyant hunting decoy 100. This sinking behavior is clearly unnatural and common among many brands of decoys on the market today.

Therefore, there is a need for a hull and keel for buoyant hunting decoys that allows for more lifelike animal behavior, while at the same time allowing for efficient and cost effective manufacturing.

SUMMARY

The present disclosure may overcome one or more of the aforementioned drawbacks by providing a buoyant hunting decoy that provides significantly improved lifelike behavior by bobbing and responding naturally to water movement while floating in the water.

The following discussion is presented to enable a person skilled in the art to make and use embodiments of the invention. Various modifications to the illustrated embodiments will be readily apparent to those skilled in the art, and the generic principles herein can be applied to other embodiments and applications without departing from embodiments of the invention. Thus, embodiments of the invention are not intended to be limited to embodiments shown, but are to be accorded the widest scope consistent with the principles and features disclosed herein. The following detailed description is to be read with reference to the figures, in which like elements in different figures have like reference numerals. The figures, which are not necessarily to scale, depict selected embodiments and are not intended to limit the scope of embodiments of the invention. Skilled artisans will recognize the examples provided herein have many useful alternatives and fall within the scope of embodiments of the invention.

Referring to FIG. 2, an illustrative example of a buoyant hunting decoy 200 is depicted. The buoyant hunting decoy 200 includes a hull 202 attached to and extending downwardly from an upper decoy portion 210. The upper decoy portion 210 is substantially hollow and is colored to resemble a water fowl, such as a male mallard duck. It is contemplated that the upper decoy portion 210 may be formed to resemble any species of waterfowl or other animals that may be hunted with buoyant hunting decoys. It is also contemplated that the hull and weighted keel may be used outside of traditional hunting decoys.

The hull 202 and the upper decoy portion 210 are designed to be joined together to form a substantially waterproof unit. In some instances, the hull 202 and the upper decoy portion 210 may be integrally formed in the same manufacturing process. Furthermore, it is contemplated that the buoyant hunting decoy 200 be manufactured by a variety of techniques allowing for a wide range of materials. For example, the buoyant hunting decoy 200 be formed by wood carving or any number of plastic forming techniques such as injection molding, blow molding, and a variety of casting methods. In some instances, the hull 202 and the upper decoy portion 210 are provided as the same material, for example, high density polyethylene (HDPE). In other instances, both the hull 202 and the upper decoy portion 210 are constructed from a blend of HDPE and low density polyethylene (LDPE). It is also contemplated that the hull 202 and the upper decoy portion 210 may be constructed separately from LDPE or HDPE. In some configurations the hull 202 and the upper decoy portion 210 may be manufactured separately and then assembled into a finished buoyant hunting decoy 200. In other configurations the hull 202 and the upper decoy portion 210 may be manufactured as a single piece construction. Regardless of manufacturing technique or practice, the hull 202 and the upper decoy portion 210 may be constructed of individual or blended materials to provide the best material properties for a specific portions requirements.

Turning now to FIGS. 3-6, the hull 202 is depicted without the upper decoy portion 210 so that the details and shape of the hull 202 may be clearly observed. The hull 202 includes a curved bottom wall 204 with a first keel 206 and a second keel 208 protruding downwardly from the wall 204. In some instances, the bottom wall 204 of the hull 202 is curved and is not flat like the prior art example depicted in FIG. 1. More particularly, the bottom wall 204 is convexly curved from a front end 214 of the bottom wall 204 to a rear end 216 of the bottom wall 204 (see FIG. 4). Likewise, the bottom wall 204 is similarly convexly curved from a left side 218 to a right side 220 (see FIG. 5). Therefore, the combination of the convex curves from the front end 214 to the rear end 216 and the left side 218 to the right side 220 results in the bottom wall 204 taking the form of a complex curved surface. The bottom wall 204 is curved to provide better hydrodynamic performance under varying conditions when compared to the traditional flat bottom prior art buoyant hunting decoys. In particular, the water flow under and around the hull 202 is improved and results in enhanced lifelike behavior of the buoyant hunting decoy 200, in part, due to the complex curvature of the bottom wall 204.

Still referring to FIGS. 3-6, the hull 202 also includes the first keel 206 and the second keel 208 that protrude downwardly from the bottom wall 204. The first keel 206 and the second keel 208 extend downwardly from an imaginary centerline 222 (see FIG. 3) that extends longitudinally from the front end 214 to the rear end 216 of the bottom wall 204. A first end 224 of the first keel 206 is positioned proximate to a mid-point of the centerline 222 formed by plane M (see FIG. 4) that bisects the buoyant hunting decoy 200. A second end 226 of the first keel 206 is positioned about three-fourths of the distance between the mid-point of the center line and the rear end 216 of the bottom wall. Further, the second keel 208 is positioned about midway between the front end 214 and the mid-point of the centerline 222.

In the embodiments depicted in FIGS. 2-6, the first keel 206 is located on one side of the plane M, and the second keel 208 is located on the opposite side of the plane M, with a gap G formed therebetween. In some embodiments, the length of the gap G is about the same size as the length of the second keel 208. In other embodiments, the length of the gap G may be modified to accommodate smaller or larger upper decoy portions 210. Further, in some instances, the length of the first keel 206 may be approximately twice the length of the second keel 208.

The first keel 206 is provided in the form of a body with a slanted front wall that extends down, flattens out, and terminates at a rounded foot. The foot includes a closed line retention hole 236 designed to receive a line. The body also includes recesses 230 on opposing sides of the first keel 206 that are designed to receive one or more weights 228. The recesses 230 are sized to correspond to the shape and size of the weights 228. The weights 228 are coupled to the first keel 206 through a central wall (not shown) by a pair of rivets 232. It is contemplated that the weights 228 may be retained to each side of the first keel 206 by any number of fastening methods such as screws, glue, nails, and the like known to one of ordinary skill in the art.

The weights 228 are provided in the form of one or more thin plates (see FIG. 7) that have a curved lower surface and a substantially flat upper surface. In one instance, a single plate is provided for each side of the first keel 206. In another instance, a plurality of plates may be provided. For example, two plates may be provided for each side of the first keel 206. The weights 228 may also include a logo or another insignia on a surface thereof.

Additionally, in some embodiments, the weights 228 are designed to have a combined mass of about 85 grams for a common mallard duck decoy as depicted in FIG. 2. In other embodiments, the mass is at least 85 grams. In further embodiments, the mass is between about 70 grams and about 100 grams. It should be appreciated that the mass of the weights may be increased depending on the size of the buoyant hunting decoy 200. One illustrative example is a buoyant hunting decoy shaped and decorated as a larger Canadian goose. Regardless of the species, the hull 202 and weighted keel 206 require less mass to keep the buoyant hunting decoy 200 upright in the water as compared to prior art keels, while permitting significantly improved lifelike movement and behavior in the water. For a standard mallard or comparable duck decoy, about 85 grams (about 3.0 ounces) to about 125 grams (about 4.4 ounces) is believed to be about the minimum weight to ensure the decoy will right itself in the water if knocked over depending on the size and shape of the decoy.

It is contemplated that the weights 228 are manufactured from a corrosion resistant metal or are treated and/or painted/coated to prevent corrosion. Some exemplary metals include any number of stainless steel alloys, including but not limited to 304 stainless steel, bronze alloys, and aluminum alloys. While the use of metal may increase the manufacturing cost slightly, it is an improvement of the prior art's use of sand in the body 108 by providing a smaller volume with higher density to maximize the effects on the weight distribution and positioning close to the bottom wall 204. It is contemplated that the materials used for the weights may be made from a variety of materials known to one having ordinary skill in the art.

Still referring to FIGS. 3-6, the second keel 208 protrudes downwardly from the wall 204 and is defined by a body with a sloping surface that terminates at a front foot. The body includes a pair of recesses 234 on opposing sides of the body and numerous openings provided in the form of a closed line retention hole 236 and an open line retention hole 238. The open and closed line retention holes 236, 238 may be used to configure the buoyant hunting decoy 200 with a variety of arrangements by a hunter. It is contemplated that any number of holes or slots may be present to offer numerous configuration and line retention options to a hunter.

The second keel 208 includes a second protrusion 250 that creates a second line retention notch 252. Likewise, the first keel 206 also includes an opposing first protrusion 254 that creates a first line retention notch 256. The first and second line retention notches 256, 254 may be used with the open and closed line retention holes 236, 238 to provide storage and customizable deployment configurations for a weight line. A weight line may include a clip at one end to be attached to one of the closed retention holes 236. The excess weight line may be wrapped around both the first and second keels 206, 208 within the first and second line retention notches 256, 254. Depending on the depth of the water, the appropriate amount of weight line may be provided below the buoyant hunting decoy 200 and hooked through the open retention hole 236 to prevent the excess line from unraveling. For storage, the weight line may be fully wrapped around the first and second keels 206, 208 within the first and second line retention notches 256, 254 and then hooked through the open retention hole 236 to prevent the weight line from unraveling.

As can be seen in FIGS. 3-6, the weights 228 are positioned adjacent the bottom wall 204 and centered on opposing sides of the centerline 222. Also, the weights 228 are positioned behind the midpoint of the centerline giving the weights 228 a rearward bias effect on the center of gravity of the buoyant hunting decoy 200. The reward bias of the center of gravity is also affected by the reduction of mass in the second keel 208 from the recesses 234. The combination of the complex curve shape of the bottom wall 204 and the weight distribution by positioning the weights 228 below a reward portion of the buoyant hunting decoy 200 and just below or adjacent to the bottom wall 204 permit significantly improved lifelike behavior of the buoyant hunting decoy 200.

The weight distribution and shape of the hull 202 also permit the improved natural lifelike bobbing and movement in the water to persist longer that the prior art buoyant hunting decoy 100. The weight and position of the lower body 108 of the prior art buoyant hunting decoy 100 has a severe dampening effect that is significantly overcome by the shape and weight distribution of the hull 202. By overcoming the dampening effect of the prior art devices, the buoyant hunting decoy 200 bobs and moves longer without requiring a jerk line. Furthermore, if a hunter still desires a jerk line to increase the movement of the buoyant hunting decoy 200, less effort is required to maintain persistent movement when a hunter pulls on the jerk line attached to the buoyant hunting decoy 200. This permits the hunter to pay more attention to approaching animals attracted by the buoyant hunting decoy 200.

Furthermore, the weights 228 are also positioned parallel to an interior wall and within the recesses 230 of the first keel 206. By keeping the weight close to the bottom wall 204 and positioned vertically, the buoyant hunting decoy 200 also has improved tracking and movement in currents and/or choppy moving water. The structure of the hull 202 substantially reduces the tendency of the front end 214 to be pulled downward by hydrodynamic forces that are created by the water flow between the flat bottom hull 104 and the lower body 108 attached below the keel 106 of the prior art buoyant hunting decoy 100 as shown in FIG. 1.

The shape of the hull 202 and weighted keel 206 also provide a functional esthetic as well as improved lifelike performance. The first and second keels 206, 208 are smaller and allow the buoyant hunting decoy 200 to be deployed in a larger variety of environments from faster moving currents to shallow still waters. Furthermore, as a result of the shape, the buoyant hunting decoy 200 may be pressed into a wet bank or shoreline to appear as a nesting or resting hunting decoy with less effort that the prior art design presented.

Turning now to FIG. 7, a buoyant hunting decoy 200 is depicted with an exploded view of the weights 228 illustrating the attachment method. As shown, the weights 288 comprise four individual weights 228 that are coupled together and attached to the first keel 206 via the rivets 232 that extend through the weights 288 and the weight retention holes 242.

It is contemplated that in some configurations of the improved hull 202 the rivets 232 may be replaced by fastening mechanisms described herein that permit changing the number or mass of weights 228 coupled to the first keel 206. It is also contemplated that the number and/or mass of the weights 228 may be adjusted by a user based upon environmental conditions and/or personal preferences of the user. During different environmental conditions, on a windy day for example, a user may wish to increase or decrease the number and/or mass of the weights 228 to adjust the behavior of the buoyant hunting decoy 200 depending on the body of water that the buoyant hunting decoy 200 is to be deployed in.

It will be appreciated by those skilled in the art that while the invention has been described above in connection with particular embodiments and examples, the invention is not necessarily so limited, and that numerous other embodiments, examples, uses, modifications and departures from the embodiments, examples and uses are intended to be encompassed by the claims attached hereto. The entire disclosure of each patent and publication cited herein is incorporated by reference, as if each such patent or publication were individually incorporated by reference herein.
